Geographical distribution
Native to many European drainages, including the Seine, Rhône, North Sea and Baltic. Introduced in Ireland. Dace formerly given this name in Siberia or East Asia belong to other species and are not added to this range.
- Native range : Seine and Rhône

Identification
Leuciscus leuciscus has a streamlined outline, a forked tail and a small, slightly downturned mouth. The souffia has a more marked lateral stripe; a young chub can also mislead. Other dace species occur in French river basins: the common name alone does not confirm this taxon.
Habitat
Flowing rivers with gravel, particularly areas downstream of a riffle, are characteristic habitats. Observe a steady current seam with nearby shelter. To start, choose a stretch without submerged branches, close enough to guide the line from the bank; violent current is not an objective in itself.
Diet
Aquatic insects or insects fallen into the water, larvae, worms, molluscs and crustaceans; also filamentous algae and mosses.
Behaviour
Dace eat insects and other invertebrates in particular, on the bottom or in the drift. Examine the shoal's movements and surface feeding. Feeding depth can vary: try several depth settings instead of imposing a single depth because the spot looks like another one.
Indicative biological size
20–30 cm in the DORIS description, excluding the maximum; a descriptive range that varies between populations.
Fishing context and precautions
- Plumb a steady current seam and set up a line with a float, adjustable shotting and a single hook.
- Place the bait upstream of the chosen area, then follow it with the rod without abruptly speeding up its path.
- Control the bow in the line to read a bite and maintain an even drift.
- Repeat in the same channel; first adjust the shotting or depth if the line snags or passes too high.
A distinctive feature
After fertilisation, its eggs adhere to gravel on the riverbed.
